' mac Hlu E ifon PASTEURIZING BEER.

Be it known that I, CHARLES A. Kine, of

Mattapoisett, in the county of Plymouth and State of Massachusetts, haveinvented a new and useful Improvement in Machines Especially Adapted forPasteurizing Beer, of which the following is a specification.

My invention has for its object the production of a machine wherebybottled beer may "be expeditiously and economically pasteurized. i

The pasteurization of the bottled beer to destroy yeast-germs, &c. isordinarily accom-' -plished by heat applied to the bottles. To

this end a pasteurizing temperaturevof at least 160 Fahrenheit isrequired, andin order that the bottles may not be broken in theoperation the heat must be gradually ap-' plied and the bottlesgradually cooled-subsequently thereto.""Water-baths of varyingtemperatures, into which the bottles'are successively plunged,- arefavored in the art as a means ofpasteurization because of the ease withwhich uniformity in the determination and maintenance of the propertemperatures is thereby secured. v Ordinarily machines ofthis'water-tank type comprise several tanks or baths, the pasteurizing-bathbeing a central tank maintained at a temperature of 160 Fahrenheit orover, while attemperating-and cooling baths on either side thereof aremaintained at temperatures considerably lowersay 90 Fahrenheit. Inoperation the bottles entering the first or warming bath at atmospherictemperature are heated therein to substantially the temperature of thatbath and are then passed into the pasteurizingbath to be heated to thehigher or pas'teurizing temperature. Thence passing to a third orcooling bath the temperature of the bottles is again lowered, whereuponthey are then passed The bottles, however,

raise the temperature of that one;

ing-tank, and by a simultaneous cooling of the last tank,theseoperations being independent in the sense that there is noautomatic adjustment of temperature between the baths. 1 have conceivedthat in an apparatus of this type by placing the attemperating-tank andSpecification of Letters Patent. 1 Application filed July 20, 1899.-Serial no. 724,516.

cooling-tank in proper relation to each other and to thepasteurizing-tank there may be produced a substantial equalization oftemperature in the attemperating-tank and in the cooling-tank and thatsuch'condition may be continued without the further application of heatother than that admitted to the pasteurizingtank. Accordingly I haveconstructed a machine which, briefly, comprises the three-tanks .inalinement, a bottle-carrier passing longi:

tudinallythrough them, and in addition a communication from thepasteurizing-tank to point of the warming-tank remote from thepasteurizing-tank to the bottom'of the cooling-tank, and an overflowfrom the coolingtank. The pasteurizing-bath I maintain at a constanttemperature in the usual way by the injection of steam. Although in thismachine the action of the water-currents whereby the heat is transmittedfrom tank to tank the warming-tank, a communication from a is to 'me notentirely certain, the logical explanation is as follows: The steamcondensing in the pasturizing-tank increases the volume .of watertherein, and this tank being in connection with the first tank a currentof hot water enters the latter and tends to neutralize thecooling effectof the cold bottles entering therein. The portion of the warming-bathremote from the pasteuring-tank is of courseleast aflected by theincoming current of hot water, and'therefore tends to assume a lower.

temperature than therest of that bath. From this point of thewarming-tank, however, is the communication to the cooling-tank, and byreason of the increase in volume in the former, owing'to the hot-watercurrent mentioned, a current to the latter takes place. Such currentbeing from the colder portion of the warming-bath tends on entering thecooling-tank to neutralize the heating effect of the bottles coming fromthe pasteurizingtank, and thecold water from the warming tank enteringthe bottom of the cooling-tank raises the water-level thereof and causesthe hotter water at the surface to overflow to the waste-pipe. I I

Having set forth the general principle of my invention and my embodimentofthe same, 7 I will now describe'the invention in detail,

reference being had to the accompanying drawings, in which Figure 1- isa broken'longitudinal diagrammatic section of an apparatus embodying myinvention, Fig. 2 being a plan thereof.

Fig. 3' is a sectional view of the left-hand end of lIO passage throughthe water-tanks.

the apparatus, showing a portion of the first tank. Fig. 4 is asectional view showing the arrangement of parts at the division betweenthe first and second tanks. Fig. 5 is a corresponding view taken at thedivision between the second and third tanks. Fig. 6 is a sectional viewshowing the right-hand end of the apparatus; and Fig. 7 is a plan viewofthe receiving-table at the right of Figs. 1 and 2 showing also a portionof the conveyer in plan.

Referring to the drawings, my machine is shown as a long trough-likestructure with end walls a and cl and partitions at b and c to formthree tanks A B C, the central tank B of which is the pasteuriZing-tankand the tanks A and C the attemperating-tanks. The tanks have pipeconnections H (see Figs. 1, 4, and 5) to a water-supply. In operationthe water is maintained in the tanks at the level indicated in thedrawings by the dotted line E.

For initially heating the several baths to their respective operatingtemperatures the tanks are provided with steam connections J. (See Figs.1, 4, and'5.) These connections enter the tanks and are there perforatedto permit steam to be injected into the water of the tanks andcondensed. Ordinarily in practicing my invention the steam connectionsto the tanks A and C are used only in bringing the baths to the propertemperatures prior to the operation of the machine, after which they areclosed, the temperatures of the baths A and C being then automaticallymaintained, as heretofore described.

For providing communication from tank B to A there is in the partition 6(see Figs. 1 and 4) at the water level an opening m, and through thisthe hot water formed steam condensing in B passes into tank A. From apoint in the tank A just below the waterline apipe M of largecross-section passes around outside of the tanks and enters the tank 0at a pointnear the bottom thereof. (See Figs. 1, 6, and 7.)Communicating with tank C at the water-level therein (see Fig. 5) is adrip or waste pipe m through which hot water from the surface of bath 0passes to the sewer or waste through pipe K. For draining the threepipes at will each is provided with a drain-pipe K, controlled bysuitable valves.

. For feeding the bottled beer expeditiously through the machine I haveprovided the following meansr Extending longitudinally through the threetanks is a way having rails c. This way or track passes from one tank tothe other over the partitions Z) and 0 at inclines. On the track is anendless carrier comprised of slats a, linked, as at 6', (see Figs. 3 and7,) and engaging the rails e by means of rollers 0 with which the linksat intervals are provided. The rollers also engage a guardrail 6 wherebythe carrier is maintained properly submerged and on the railway duringFrom f f f and around under the machine to the starting-point at tank A.The sprocket f is the carrier-driving gear and is driven from pulley F(see Fig. 7) by means of a wormgear F.

In order that the beer, which is conveyed in cases, may be rapidlysupplied to the carrier, I provide a roll or idler g. The case is slidby the operator over the rolls until it is engaged by the carrier. Thatthe carrier may properly engage the cases and hold them in positionduring the operation the slats c are at intervals provided with cleats 6one of which engaging the case from the rear holds it stationary on thecarrier in advancing through the baths and up the inclines of therailway, while another cleat in the front of the case prevents it fromsliding out of position when going down the inclines. That the carriermay be automatically relieved of the cases after passage through tank Cthere is provided a second set of rollers or idlers d, (see Fig. 7,)over which the cases are slid by the action of the carrier, asillustrated.

The operation of my machine is as follows: The tanks are first filledwith cold water through the pipes H to the level E, after which thesepipes are closed. The steam-pi pes J are then opened to heat the waterin the pasteuriZing-tank B to a temperature of 160 Fahrenheit or overand the water in the tanks A and C each to a temperature of about 90.The steam-pipes to the tanks A and U are then closed and the steam-pipeto the tank B adjusted to supply heat to maintain the baths at theproper temperatures during the pasteurizing process. The baths beingthus prepared the process is commenced by the operator starting a caseupon the carrier by sliding the same over the roller 7. The case thusfed to the carrier is engaged by a cleat c and fed forward into the bathA. Here the beer in the case is heated to a temperature of about 90 andin turn the bath is slightly cooled by the beer. Passing from tank A thecase now enters the bath B, where the temperature of the beer is raisedto at least 160 Fahrenheit and the beer pasteurized, this bath beingalso slightly cooled by the beer. The slight cooling eflect of the beeris, however, immediately corrected by the steam constantly injected intotank B and there condensed, this condensation, as stated, causing anoverflow from Bto A, thus raising the temperature of A to thetemperature had before the entrance therein of the beer, whereupon, inturn, there is caused an overflow of the slightly cooled water throughconnection in to tank (I. The beer at 160 passing on from tank B to tankC is there cooled to about 90 The tendency of the hot bottles onentering C from B to raise the temperature of bath C is counteracted bythe cool water coming from A, which entering the bottom of the tank C isdiffused updrained and cleaned through the soa'aee ward, causing anoverflow of Warm water from automatically and continuously repeated.Al"- ter the quantity of beer desired to be pasteurized has been sotreated the tanks may be pipes K by opening the valves therein.
